[Stoves] EWB Princeton in Huamanzana

[Tom Miles]

Charlie,

This is a great time to support the EWB Huamanzana effort. I'm sure that
folks will pitch in. It sounds like you've give up or at least modified the
Inkawasi approach.   

Best regards to Shannon and the others. 

Kind regards,

Tom miles

Subject: [Stoves] EWB Princeton in Huamanzana

Hello everyone, and now I am REALLY grateful for all of your postings to the
web over the years - I can access all of your expereinces easily, even from
almost remote places in Peru!  The EWB Princeton student project building
chimney stoves is in a little village past electricity, a few hours from
Trujillo Peru.  It has 35 homes and is in a river valley in the foothills of
the Andes - everything is just sand, stones, and ancient mountains with no
vegetation - it only rains every 12 to 15 years here, and this winter there
is just a trickle of water that is diverted for irrigation.  Huamanzana has
almost no technology except for the small solar electricity system intalled
by these engineers in the past - a few public place lights and a battery
charging system for the batteries they use in the LED lanterns that each
house was issued (it costs them $.30 USD every 2 weeks).
   
  We are building a custom plancha chimney stove for each household,
basically based on the ONIL concept (though we have no plans for it or
similar), since the submerged pot design did not work well last year (leaks,
and too many different pot sizes).  Right now they cook in a trench between
bricks, on a platform that the guinea pigs live beneath, and the copius
smoke exits through the holey walls and roof (so the IAP issues are not as
bad as I feared).  As usual they balance several pots at a time on the
bricks, and feed scarce wood the size of your arms into the space too
quickly.
   
  They will find the diminished response time, efficiency, fire visibility,
and water boiling time of the future stoves to be dreadful, but we will make
the stoves (sized to each cook) attractive to compensate.  I hope.
   
  No time for too many details here, but I would like to mention a few
things that I could use a bit of help on:
  - ideas on the use of stone for construction, since they only use adobe
now
  - stone or metal SIMPLE burners for burning their trash completely (same
for making charcoal from biomass)
  - using biomass in a plancha stove, to save trees
   
  I only get email every few days in a small town a few hours away so send
only a few (with a link or two - your time is valuable, and mine very
scarce) to me at csellers42 at yahoo.com, as well as too the list if it might
be of interest to all.  Just a few emails with key information would be
great, to use the few materials I have (just bricks, floor tile, stone,
cement, sand, some custom refractory brick luckily, and a bad blacksmith
using scrap iron) to make the most difference.
